摘要(Abstract)：

针对目前燃煤机组在启动阶段燃料控制中存在的操作设备繁复、控制参数过多、优化手段单一以及启动时间过长等一系列问题，提出了一种面向对象动态学习的燃煤机组燃料全程控制方法。通过将整个燃料全程控制对象化、阶段化，动态学习各个阶段各个系统当前工况，自适应产生燃料智能控制指令，实现从机组点火到投入协调控制的全过程燃料智能控制。在某1 050 MW机组上进行了功能验证，实际运行结果表明，该控制方法在整个运行过程中具有较强的时效性与智能性，能大大缩短机组启动时间，提高机组整体自动化水平。
In response to problems during the startup of coal-fired generating units, including intricate equipment operation, an excess of control parameters, limited optimization techniques, and protracted startup time, an objectoriented dynamic learning method for whole-process fuel control within coal-fired generating units is introduced.This method entails the segmentation and objectification of the entire fuel control process, allowing for the dynamic acquisition of the current operational status of each system at every stage. Consequently, adaptive fuel intelligent control directives are generated, facilitating the realization of intelligent fuel control throughout the entire sequence, from unit ignition to coordinated operation. Functional validation has been performed on a 1,050 MW unit, and practical implementation confirms the method's capacity for efficient and intelligent operation throughout the entire process, significantly reducing unit startup duration, and elevating the unit's overall level of automation.
